I don't think anyone would create a PR stunt that has you assaulting your own Mother ... He could have easily gotten press by having a brawl in a pub. So, this seems real. But I do find it curious that his sister would embarrass him, so publicly and irreversibly, over a heated argument and possible shoving match, on what is one of the most important days of his career. Most parents and siblings would opt to handle it privately and not embarrass a member of their own family so publicly ...
